Descriptions:
Psoralen crosslinking between human immunodeficiency virus type 1 RNA and primer tRNA3(Lys).[1]
Psoralens and UVA light selectively inhibit binding to the higher-affinity EGF receptors, an effect analogous to that of the phorbol ester tumor promoters, since EGF is a growth-regulatory peptide, the ability of psoralens and UVA light to inhibit EGF binding may underlie the biologic effects of these agents in the skin.[2]
Psoralen induces DNA adducts are substrates for the base excision repair pathway in human cells.[3]
Psoralen induces a persistent intracellular DNA damage at a specific site and to afford prolonged transcription inhibition.[4]
